100
This is how consistent your measure is.
What is reliability?
100
Event A has a probability of occurring = .50. Event B has a probability = .50. This is the probability of Events A and B occurring simultaneous is they are mutually exclusive.
What is 0?
100
A _______ sample size increases the likelihood of rejecting the null hypothesis.
What is larger?
100
A random sample of n = 45 individuals is selected from a population with μ = 20 and σ = 5, and a treatment is administered to each individual in the sample. After treatment, the sample mean is found to be M = 22.2. For this example I would conduct this hypothesis test.
What is a z-test?
100
This is how you get your standard error from your standard deviation
What is divide the SD by the square root of n?
200
This is when you administer the same measure to someone multiple times and examine how similar the scores are.
What is test-retest reliability?
200
Which is higher: the probability of picking a red face card or the probability of picking an ace from a standard deck of cards.
What is picking a red face card (6/52)?
200
This is always the null hypothesis for a paired samples t-test.
What is μD = 0?
200
If I want to compare the average height of males and females, I would conduct this test.
What is an independent samples t-test?
200
This is when you obtain a score for every person in the population.
What is a census?
300
This is the extent to which you can say the change in the DV is due to your IV
What is internal validity?
300
An event that will always happen has a probability of this.
What is 1?
300
If you pick the correct direction, it is ________ to reject the null hypothesis using a directional test instead of a nondirectional test.
What is easier?
300
I administer a smoking intentions questionnaire to a group of smokers. The smokers then complete a 2-week intervention to decrease smoking. After the 2-weeks, I give them the smoking intentions questionnaire. To evaluate whether my intervention worked, I would conduct this test.
What is a paired samples t-test?
300
In this sampling technique, everybody in the population has an equal probability of being selected.
What is simple random sampling?
400
If I correlate the scores of my items on my depression scale and find that are not related, my ______________ is low.
What is internal consistency?
400
This is when you list out all possible outcomes of an experiment.
What is sample space?
400
A researcher concludes based on her sample that mules on average eat less than horses when in reality horses eat more than mules. The researcher made this type of error.
What is there was no error made?
400
A sample of n = 15 is taken from a population with µ = 25 and σ = 2. After a treatment is administered, the sample M = 29. For this example, I would conduct this test?
What is a one-sample t-test?
400
Judgmental sampling is this type of sampling technique.
What is nonprobability?
500
This is how well your measure captures all aspects of your construct of interest.
What is content validity?
500
If I have 10 golf balls (3 yellow, 4 red, and 3 green) and the first 2 golf balls I pick are both yellow, this is the probability of picking a third yellow golf ball if I am not sampling with replacement.
What is 1/8?
500
If a treatment has a very small effect, this is the likely outcome for a hypothesis test evaluating the treatment.
What is a Type II error?
500
If I am interested in whether ice cream sales and deaths due to drowning are related, I would conduct this test.
What is correlation?
500
This type of qualitative research begins with a set of generative questions, then identifies core concepts as data are gathered, with linkages developed between the core concepts and the data.
What is grounded theory?
